FORGNG-MACHINE Specification of Letters Patent.

Patented Oct. 15, 1907.

Application iiletl'f'ebruary 23,1905. Serial No. 246,835-

To all whom it may conce/"o:

Be it known that ilu-Jorn; R. BLAKnsLnn, Jr., a citizen of the UnitedStates, and a resident of Cleveland,

county o1" Cuyahoga, and State oi Ohio, have invented a new and usefulImprovement in Forging-Machines, of which the following is aspecification, the principle of the invention being herein explained andthe best mode in which I have contemplated applying that principle, soas to distinguish it from other inventions.

My invention relates toupsetting machines for imparting to hot metalvarious required forms, through the medium o1' suitable dies and formingtools.

Said invention relates particularly .to upsetting or forging machinessuc-has is shown and described in Patent No. 737065 issued to John R.Blakeslee, August 25, '1903.tho machine to which my invention is appliedbeing of the same general form as that of said patent.

The ,object o f my invention is to effect a forging or upsetmg.operationnt two ends ol the work siniultaneonsly und to effect such operation inan economical and cllicicnt manner.

My invention consists of means hereinafter fully described andparticularly set forth in the claims.

The annexed drawings and the following description set forth in detailcertain means embodying the invention, suchdisclosed means constitutingbut one of variousmechanical -forms in which the principle of theinvention may be used.

In said annexed drawings :-Figure l represents a plan ol a portion of anupsetting or forging machine such as is shovm in the above-named patent,the construction being shown as modified by the introduction of myinvention. Fig. 2 represents a partial plan and a partial horizontalsection taken upon the planes indicated by the Vlines 2 2, Fig. 3. .Fig-3 represents a vertical section of a portion of the machine-frame,die-parts and die-slide and a portion of one of the operating linksconnected with the latter, such section being taken upon the planeindicatedby line 3 3 of Fig. l. Fig. 4 represents a verticalsection ofthe parts shown in Fig. 3

taken upon the plane lindicated by line4-4 in said tigure. Fig. 5representsan-en'd view of one ol the dieparts, parts connected therewithbeing shown in vorticalsection. Fig. 6 representsa perspective View oi'one o said die-parts. Fig..7 represents elevationalviews upon both endsof the same structure simultaneously.

The general construction and operation of the upsetting machine to whichmy invention is applied being described in the above-named patent, lshall merely describe those parts directly pertaining to my'improvement.As in said patented machine, the machine herein described is providedwith a reciprocable headerslide (not shown) and heading-tool A mountedthereon. This header-slide cooperates with a die-slide .ll whosereciprocatory path is at right angles with respect to the reciprocatorypath ell the header-slide and headingtool. In connection with these twoelements is employed a two-part die, the one part O of which is mountedadjacent to the vertical bearing surface b formed on the frame B, such,surface heilig, as shown, parallel with the direction ol reciprocationof the header-slide and tool, as shown in Fig. l. The bottom of saiddiepart C is formed with a tongue c which slides in a groove b/ formedin the frame, so that the said die-part is movable toward and from theabutment-plate BE ofthe machine, the direction of such movement being,as will be readily understood, the same as that ot' the headerslide.Seated in a bore c of said die-part is a plunger c'-` which projectsfrom the front face c3 of the die-part and is actuated to assume theposition shown in Fig. 2 by a coil-spring c. The said plunger isprovided with a stem c5 which projects through the back end of thediepart and is provided with nuts c which hold the plunger in place, aswill be readily understood. v The Said spring c4 is of a strength .suchas to move the die-part away from the abutment plate to the full extentofthe possible projection of the plunger therefrom, when such die-partis free to so move. The inner or working-face c'T is provided with anintaglio e8 which is ol a form such as to intersect'. the two end facesot the die-part, as shown. The particular form of intaglio shown isadapted to receive a structure which is to be operated upon at both endsto form a turn-buckle blank:

Upon that tace ol' the dic-slidl` I3 opposing the diepart C is formed anunder-cut groove 11"', Figs. l and IS, in which groove is slidablymounted a tongue c ol' the complementary die-part C. lt will thereforebe soon that this die-part is slidablo in the .same direction as isdie-part O, that is, toward and from the abutmentplate B1'. Saiddio-plate C/ is provided ith a plunger e? attached and mounted in amanner exactly similar to that ol the plunger ol die-part (l. Projectingl'roln the inner face oi die-part C are two horizontalrods c1", c1",fixed thereto and which project into two guiding bores-cil, cll,iormedin the opposing die-part t), such rods being adapted to freely slide andsnuglyifit in said bores. These rods and bores, while they allow the twodie-partsV to freely approach and recede from each other, tix auch partsrelatively to each other in the direction of movement of thereciprocatory tool A, and hence preserve the required alinemcnt ofthesaid two die-parts. A groove b3 is cut inthe frame in which slidesaguiding tongue b5 formed in slide `B', Fig4 3, whereby the propermovement of said slide is assured: The axis of the tool A lies in astraight line containing the axis of the forming space formed by the twointaglios oi' the two die-parts, and in this line of axis also lies theaxis o the fixed tool B3 which is secured to the alultinent-plate B2. Itwill therefore bey seen that the two tools may enter the opposite endsof the forming-4 space of the die, when the die-parts are broughttogether, as shown in Fig. 2. The two tools A and 13"*Y are respectivelyprovided with shoulders b4 and a, which determine the extent of maximumentrance of said tools into thc die.

When the'header-slide and tool A are withdrawn from Contact with thedie, and the die-slide B is also in its withdrawn position7 theplungers'cz, c2, back the two die-parts away from the abutment-plate B2,as

d shown in Fig. l, and maintain such position until the machine iscaused io operate, as hereinafter described. The properly prepared,heated structure to be operated upon by the tool, is now placed iu theintaglio of the die-part CV the heated en'ds thereof projecting thenecessary distance into the end portions of such intaglio. The'niachinenow being started the die-slide B moves toward the die-part C so as tobring the latter andthe die-pai C/ into contact, as shown in Fig. 2,thus securely clamping the structure to be operated upon between saidtwo parts. Immediately upon such aci-ion the tool A enters the end ofthe die an'd strikes ilu metal of the .clamped structure. Upon furtherforward movement of said tool the entire die is moved forward againstthe action of plungers c2, c'Z the actuating springs c4 o i thelatterbeing compressed. This forward movement is contined until the tool` Bi*strikes 'the opposite ond of such metal structure. Immediately followingsuch engagement of said tool, the upsetting or forging operation beginsand the forward movement of the tool A and die is continued until the`tools have entered the die to their full extent, that is, until theshoulders a and b4 abut the ends of said die, as shown in Fig. -2. ToolA is thereupon withdrawn and is followed by the die, the movement of thelatter' being effected by the spring actuated plungers. Such actioncauses the tool B to be withdrawn and -upon the continuation of theretractng movement of tool A the die resumes' its normal position, inwhich the tools A and B3 are'completely withdrawn therefrom.

Otherinodes of applying the principle of my inven tion may be employedinstead f the one explained1 changebeingniade as regards the mechanismherein disclosed, provided th'e means stated by any one oi the followingclaims or the equivalent oi such stated means be employed 'I I thereforeparticularly point out and distinctly claim as my invention ,l
